Dew pond

A dew pond is an artificial pond usually sited on the top of a hill, intended for watering livestock. Dew ponds are used in areas where a natural supply of surface water may not be readily available. The name dew pond (sometimes cloud pond or mist pond) is first found in the Journal of the Royal Agricultural Society in 1865. Despite the name, their primary source of water is believed to be rainfall rather than dew or mist.

Construction

They are usually shallow, saucer-shaped and lined with puddled clay, chalk or marl on an insulating straw layer over a bottom layer of chalk or lime. To deter earthworms from their natural tendency of burrowing upwards, which in a short while would make the clay lining porous, a layer of soot would be incorporated or lime mixed with the clay. The clay is usually covered with straw to prevent cracking by the sun and a final layer of chalk rubble or broken stone to protect the lining from the hoofs of sheep or cattle.

A method of constructing the base layer using chalk puddle was described in The Field 14 December 1907. A Sussex farmer born in 1850 tells how he and his forefathers made dew ponds:

Pond

A pond is a body of standing water, either natural or artificial, that is usually smaller than a lake. They may arise naturally in floodplains as part of a river system, or they may be somewhat isolated depressions (examples include vernal pools and prairie potholes). Usually they contain shallow water with marsh and aquatic plants and animals. A few animals also make their home in ponds, including both alligators and beavers. The type of life in a pond is generally determined by a combination of factors including water level regime (particularly depth and duration of flooding) and nutrient levels, but other factors may also be important, including presence or absence of shading by trees, presence or absence of streams, effects of grazing animals, and salinity.

Ponds are frequently human-constructed. In country side farmers and villagers dig a pond in their backyard or increase the depth of an existing pond by removing layers of mud during summer season. A wide variety of artificial bodies of water are classified as ponds. Some ponds are created specifically for habitat restoration, including water treatment. Others, like water gardens, water features and koi ponds are designed for aesthetic ornamentation as landscape or architectural features. Fish ponds are designed for commercial fish breeding, and solar ponds designed to store thermal energy.

Ponda, Goa

Ponda (pronounced /fɔɳɖɛ̃ː/) (Konkani: Fonda, Portuguese: Pondá), also known as Fonda, is a city and a municipal council in the North Goa district of Goa, India. Located in the central area of Goa, Ponda lies 29 kilometres (18 mi) southeast of Panaji, the capital of Goa. The industrial center of the state, Ponda is home to many large factories and industrial estates, and is Goa's fastest-growing city.

History

Ponda formed part of the Novas Conquistas (New Conquests) of Portuguese India. It was ruled by the Sonde Rajas under the Vijayanagara Empire and the Bijapur Sultanate. In the 16th century, due to the absence of the Portuguese, Ponda was a safe haven for Hindus fleeing persecution by Jesuits and the Portuguese. In 1675, Chhatrapati Shivaji Maharaj seized Ponda from the Bijapur Sultanate. It remained part of the Maratha Empire until 1764. Under Shivaji, Saundekar Raja was the vassal of Ponda.

The forests of Ponda were ideal places for Hindus to form makeshift temples with the idols they had salvaged from the broken temples of Sashti. These makeshift temples were slowly renovated as the Hindus gained prosperity. Now, most of the major Hindu temples in Goa are found in Ponda.

Dew

Dew is water in the form of droplets that appears on thin, exposed objects in the morning or evening due to condensation. As the exposed surface cools by radiating its heat, atmospheric moisture condenses at a rate greater than that at which it can evaporate, resulting in the formation of water droplets.

When temperatures are low enough, dew takes the form of ice; this form is called frost.

Because dew is related to the temperature of surfaces, in late summer it forms most easily on surfaces that are not warmed by conducted heat from deep ground, such as grass, leaves, railings, car roofs, and bridges.

Dew should not be confused with guttation, which is the process by which plants release excess water from the tips of their leaves.

Formation

Water vapor will condense into droplets depending on the temperature. The temperature at which droplets form is called the dew point. When surface temperature drops, eventually reaching the dew point, atmospheric water vapor condenses to form small droplets on the surface. This process distinguishes dew from those hydrometeors (meteorological occurrences of water), which form directly in air that has cooled to its dew point (typically around condensation nuclei), such as fog or clouds. The thermodynamic principles of formation, however, are the same. Dew is usually formed at night.

Degu

The degu (Octodon degus, /ˈdeɪɡuː/) is a small caviomorph rodent that is endemic to the Chilean matorral ecoregion of central Chile.

It is sometimes referred to as the brush-tailed rat, and is also called the common degu, to distinguish it from the other members of the genus Octodon. Other members are also called degus, but they are distinguished by additional names. The name "degu" on its own, however, indicates either the genus Octodon or, more usually, O. degus. Degus are in the parvorder Caviomorpha of the infraorder Hystricognathi, along with the chinchilla and guinea pig. The word degu comes from the Mapudungun dewü (mouse, rat).

Description

The degu is a small animal with a body length of 25.0 to 31.0 centimetres (9.8–12.2 in) and a weight of 170 to 400 grams (6.0 to 14.1 oz). It has yellow-brown fur above and creamy-yellow below, with yellow around the eyes and a paler band around the neck. It has a long, thin tail with a tufted black tip, dark sparsely-furred ears, and pale grey toes. Its fifth toe is small with a nail, rather than a claw, on the forefeet. Its hindfeet are bristled. Its cheek teeth are shaped like figures-of-eight, hence the degu's genus name "Octodon".
